I have a gripper. Mine does not have speakers thou. I use mine all the time as I find long periods of play with out it gives me cramps. Holding the thin DS is no where near as comfortable as holding the gripper handles. Mines son uses one as well. I find that he drops his DS far less as he has the big handles to hold onto.
A game like Call of Duty 4 cannot be played comfortable for a long period without a gripper.
